Oslo og Akershus Gulls: Glaucous Gulls

Late yesterday evening, a Glaucous Gull where found by John Martin Mjelde, Carsten Lome and Morten Helberg at Vaterland in Oslo. We desided to take a trip to get photos and look at this rare OA bird. We stopped at Bjørvika, and imminently saw a Glaucous in Bispevika. We thought that this was the bird from Vaterland the day before (only 500 meters away), but when John Martin came and said that it had been seen a Glaucous in Vaterland at the same time as we send BMS-message about our gull, it was clear that it wasn't the same bird! This is extremely rare in OA, and I think it is the first time two Glaucous is seen at the same time here. Still, there could have been some communication error, so we had to take a look at the bird at Vaterland. When we came up, there wasn't any Glaucous to be seen anywhere, but after a while it showed up. But was this the same bird that we had said earlier in Bjørvika. After image studies it is clear that there was two Glaucous Gulls in Oslo this day!
